Mechanized feeders are used to bring components to be fed, from a disorderly state into the required orientation in required quantity for a particular process. Present study has been carried out with regard to the analysis of performance of a Rotary Hook feeder under certain variable factors. For this, the above-mentioned feeder has been developed. A series of experiments were carried out on cylindrical parts, and effect of different input parameters on the feed rate was studied graphically. Experimentation shows that the performance of this feeder depends upon various factors such as part population, number of hooks, speed, part sizes and blind/through-holed parts. However, only the first three parameters have been studied in the present case, and a mathematical model has been formulated. The design of experiments is done using 23 full-factorial method. Significance of individual factors as well as their interactions is examined using Design Experts Software. Analysis of Variance (ANOVA) method is used to predict proficiency of the model. This model also provides optimized feed rate for appropriate process parameters under given constraints.

Anteromedial foot bimalleolar angle (FBM), an objective assessment of deformity and correction, was correlated and compared with Pirani scores 0.5-2, 2.5-4, 4.5-6 as grouped I to III for mean and SD in 244 club feet in 137 children. The mean FBM angles of groups I to III were 79.728, 68.48, and 53.278, respectively. The FBM angle gives an objective assessment of the severity of deformity and can be used as objective evidence of improvement/deterioration of deformity.
